Taking cover behind a large tree, an Associated Press photographer pointed his camera toward a Beirut apartment building the Israeli military warned was in its sights.

According to The New York Post, the multi-story building was reportedly located in the Tayouneh neighbourhood, next to Horsh Beirut, a city park. The viral video of the incident showed that the impact of the missile attack was so catastrophic that it caused the entire structure to collapse instantly within a few seconds.

At least 18 people were killed, including four children, and 60 were wounded in an Israeli strike on Monday near Beirut's main government hospital, the health ministry said on Tuesday.
